The vast majority of marijuana-based arrests in the State of Texas are Misdemeanor-B "Possession of Marijuana Under Two Ounces", punishable by up to 180 days in jail and a $2,000 fine. Very rarely do district attorneys seek a jail sentence in misdemeanor possession of marijuana cases, and frequently my clients will face only a deferred adjudication probation or diversion program and the related fines and community service, with no arrest on their record after completion of their plea agreement and a filing for non-disclosure.
One of the most damaging criminal charges in the State of Texas is Driving While Intoxicated (DWI), which may be charged for having a blood alcohol content (BAC) level over .08 or some combination of drugs and alcohol that lead law enforcement to believe you're a danger to yourself or others while driving or attempting to drive a vehicle.
Assault charges will follow you your entire life - you should never face an assault case without an attorney. The moment you get a call from a detective to give a statement, hire an attorney. The crime of Assault is based on unwanted contact between the "victim" and a defendant, so even the simplest "brushing past" or "pushing" may result in a case being filed. However, detectives and district attorneys do consider the facts from all sides when they have enough information to do so.
